Port Advanced Setting
There are 11 advanced functions that can be configured in this screen.
•
Volume Gain Control:
Two modes are available. The fixed gain
control means the device is supported to supply a constant level of
amplification.
The adaptive mode means a specified power level is produced at the
output during periods of active speech.
•
Jitter Buffer Mode
: Three jitter modes are available. The fixed mode,
which is the default mode, is a simple first in first out mode, with a
fixed jitter buffer delay.
The adaptive mode optimizes the size of the jitter buffer delay in
response to network conditions.
The sequential mode is also a fixed jitter buffer delay mode, but in this
mode the jitter buffer function looks at the packet number for dropped
or out of sequence packet problems.
•
Jitter Buffer Delay:
This parameter represents the delay in
milliseconds that the jitter buffer waits before it transmits the data
samples that are collected from the host processor to the CODEC
.
•
Echo Canceller Delay:
This is the function that filters out echoes
occurred during periods of active speech.
•
VAD (Voice Activity Detection):
If this box is checked, only a certain
level of voice volume will be send out as voice packets. This function
is designed to save the bandwidth.
•
CNG (Comfort Noise Generation):
Check this box to enable the
Comfort Noise Generation function. When no one is talking on a call
this feature will generate comfort noise in the background so you know
the call is active.
